How to stop the 'gem' utility from accessing my home directory?

Question

When I run

gem install 

command the gem utility tries to access my home directory. It contains some non-latin char

Answer 1

Just change HOMEDRIVE and HOMEPATH before running gem, and restore after (if needed).

I've changed my gem.bat like this:

@ECHO OFF
SET _HOMEDRIVE=%HOMEDRIVE%
SET _HOMEPATH=%HOMEPATH%
SET HOMEDRIVE=E:
SET HOMEPATH=/Dev/Ruby
IF NOT "%~f0" == "~f0" GOTO :WinNT
@"ruby.exe" "E:/Dev/Ruby/bin/gem" %1 %2 %3 %4 %5 %6 %7 %8 %9
GOTO :EOF
:WinNT
@"ruby.exe" "%~dpn0" %*
SET HOMEDRIVE=%_HOMEDRIVE%
SET HOMEPATH=%_HOMEPATH%

E:/Dev/Ruby/ is my Ruby path. It seems that HOMEPATH can be changed to anything else with ASCII only characters in path.

Answer 2

just run postinstall file pi.bat or pi.sh this file is in ./RubyDevKit/postinstall.

this worked for me. it seems that installer of cygwin broke my settings.

Answer 3

Restart the command prompt console as something might have jacked it up. I had the same issue, and restarting the console reset my environment.

Answer 4

If you GEM_PATH is set to your user directory, it will still access it. Try changing GEM_HOME and GEM_PATH.

Answer 5

Perhaps try changing the value of the GEM_HOME environment directory?

Answer 6

It's simpler to write:

@ECHO OFF
SET HOMEPATH=
IF NOT "%~f0" == "~f0" GOTO :WinNT
ECHO.This version of Ruby has not been built with support for Windows 95/98/Me.
GOTO :EOF
:WinNT
@"ruby.exe" "%~dpn0" %*

In this case you don't need to write your path and can replace or redistribute with file for new installations
